The effect of an ice-cold water (ICW) bath as a recovery intervention from aerobic exercise on the oxidant-antioxidant balance in healthy ice swimmers was determined. Twenty ice swimmers aged 31.2 ± 6.3 years performed a 30-min cycloergometer exercise test at room temperature (20°C, RT), followed by recovery at RT or in a pool of ice-cold water (ICW bath, 3°C, 5 min). Blood for laboratory assays was collected from the basilic vein two times: before the exercise (baseline) and 40 min after the RT or ICW recovery. The concentrations of plasma and erythrocytic thiobarbituric acid reactive substances (plTBARS and erTBARS, respectively), serum concentrations of 8-iso-prostaglandin F2α, 4-hydroxynonenal and malondialdehyde, along with the erythrocytic activities of catalase (CAT) and superoxide dismutase (SOD), as well as the serum level of total antioxidant capacity, were assessed. No statistically significant changes were observed. However, a statistically significant negative linear correlation between the erTBARS concentration and the SOD activity was found 40 min after the combination of exercise/RT recovery (r=-0.571, P<0.01). The baseline CAT and SOD activities were also linearly correlated (r=0.469, P<0.05). Both the 5-min ICW bath and the 30-min aerobic exercise have practically no impact on the oxidant-antioxidant balance in healthy ice swimmers.
本研究旨在确定冷水浴（ICW）作为有氧运动恢复干预措施对健康冰泳者氧化还原平衡的影响。20名年龄在31.2±6.3岁的冰泳者在室温（20°C，RT）下进行了30分钟的蹬车运动测试，随后在RT环境或冷水池中恢复（ICW浴，3°C，5分钟）。在运动前（基线）以及RT或ICW恢复后40分钟，从贵要静脉采集血液用于实验室检测。检测血浆和红细胞中硫代巴比妥酸反应性物质（分别为plTBARS和erTBARS）的浓度、血清中8-异前列腺素F2α、4-羟基壬烯醛和丙二醛的浓度，以及红细胞中过氧化氢酶（CAT）和超氧化物歧化酶（SOD）的活性，还有血清总抗氧化能力水平。未观察到统计学上的显著变化。然而，在运动/RT恢复组合后40分钟，发现erTBARS浓度与SOD活性之间存在统计学上显著的负线性相关（r=-0.571，P<0.01）。基线时CAT和SOD活性也呈线性相关（r=0.469，P<0.05）。5分钟的ICW浴和30分钟的有氧运动对健康冰泳者的氧化还原平衡几乎没有影响。
